Maritime transportation have always been the dominant support of global trades. Hence, the safety of vessels is critical to the global economy. Modern passenger vessels  are commonly protected with sprinkler system and fire extinguishers as well as fire alarm system. Standards outlines special requirements and approvals for system components and equipment used in maritime transportation. Luxurious passenger vessels may use high pressure water mist for protection. It provides the desirable level of protection at minimal water consumption. Engine rooms are usually protected by either clean agent fire extinguishing systems or high pressure water mist system. Compressed air-foam system may be an acceptable alternative for the protection of engine rooms. Large passenger terminals are usually protected with sprinkler system and fire alarm system. Cargo ships may require different systems based on the nature of raw materials or goods in which they deliver.
